Description

Technical Field

[0001] The utility model belongs to the technical field of 1-methylcyclopropene powder production, and particularly relates to an ultrafine pulverizer for 1-methylcyclopropene powder production. Background Art

[0002] When 1-methylcyclopropene powder is produced with high precision, an ultrafine powder pulverizer is generally used for ultrafine crushing. However, 1-methylcyclopropene is active at normal temperature and pressure. Although it has certain stability when prepared into powder, 1-methylcyclopropene still continuously turns into gas. Especially when it is rapidly ultrafinely crushed in an ultrafine pulverizer, under high-speed friction and shear, the 1-methylcyclopropene powder will get hot, and the gas conversion speed will accelerate. Currently, the existing ultrafine pulverizers cannot handle this part of 1-methylcyclopropene gas. When collecting 1-methylcyclopropene powder, if this part of the gas is allowed to escape, it will not only cause waste, but also cause certain harm to the body after being continuously inhaled by workers. Content of the Utility Model

Under the action of negative pressure, the ultrafine powder at the bottom of the machine body shell 21 is sucked into the powder collection tank 7 through the discharge pipe 6. At the same time, the 1-methylcyclopropene gas generated under the action of natural volatilization and heat also enters the powder collection tank 7 under the action of negative pressure. Then, under the continuous action of negative pressure, the gas passes through the filter plate 72 and enters the air duct 8, and then enters the collection tank 10 through the pump 9 for storage. The ultrafine powder is blocked by the filter plate 72 and remains in the powder collection tank 7, which can effectively collect and store the 1-methylcyclopropene gas, avoid waste caused by gas dispersion, and avoid physical harm caused by continuous inhalation of the gas by workers. In addition, during use, put the raw material into the feeding cylinder 3 through the hopper 4.
